Configuration procedure 
1)  Configure the IP address of each interface 
Configure an IP address and subnet mask for each interface as per 
. The detailed 
configuration steps are omitted.  
2)  Configure Router A 
# Enable IP multicast routing, enable PIM-DM on each interface, and enable IGMP on 
GigabitEthernet1/0/1.  
<RouterA> system-view 
[RouterA] multicast routing-enable 
[RouterA] interface GigabitEthernet 1/0/1 
[RouterA-GigabitEthernet1/0/1] igmp enable 
[RouterA-GigabitEthernet1/0/1] quit 
[RouterA] interface GigabitEthernet 1/0/2 
[RouterA-GigabitEthernet1/0/2] pim dm 
[RouterA-GigabitEthernet1/0/2] quit 
3)  Configure Switch A 
# Enable IGMP Snooping globally.  
<SwitchA> system-view 
[SwitchA] igmp-snooping enable 
  Enable IGMP-Snooping ok. 
# Create VLAN 100, assign GigabitEthernet1/0/1 through GigabitEthernet1/0/4 to this VLAN, and 
enable IGMP Snooping in the VLAN.  
[SwitchA] vlan 100 
[SwitchA-vlan100] port GigabitEthernet 1/0/1 to GigabitEthernet 1/0/4 
[SwitchA-vlan100] igmp-snooping enable 
[SwitchA-vlan100] quit 
4)  Verify the configuration  
# View the detailed information of the multicast group in VLAN 100 on Switch A. 
<SwitchA> display igmp-snooping group vlan100
